Hi, has anyone built the Harlequin ZX 48 Max issue 2?
There is a capacitor marked on the board but not in the BOM. Its position C24
I'd appreciate if anyone could tell me the value to use.

Re: Harlequin 48 Max Issue 2
Please have a look on the attached schematic.
I would also suggest using 74HCU04 inverter instead of 74HC04.

Thanks McKlaud
47pF it is then...
I'll try the alternative inverter if there are problems. Got a bit to wait for 4.43Mhz crystals arriving.
